I halted aquarela(1) with a ^D sequence, and made sure all processes were gone. ps(1) lists no processes on the server that could possibly be using port 445 (the port aquarela listens on for the CIFS service). And yet, netstat -n showed that TCP port 445 was still in LISTEN state. Naturally, I ran
echo hangup > /net/tcp/31/ctl to relinquish the port. Now it's in CLOSED state: tcp 31 bootes Closed 445 0 :: but the port is still unusable (pre-occupied - aquarela(1) is not able to open it). Short of rebooting the CPU server, is there some way to regain port 445? Quite the annoying bug... Thanks, ak
